Application filed. Mach 9,1913. Serial No; 221,487.

To all whom it may concern Be it known that I, GEORGE A. Nonnm, a

citizen of the United States, and resident of Genesee, inthe county of Waukesha' and State of Wisconsin, have invented certain new and useful Improvements in Fluid-Fuel Burners; and I do hereby declare that the following is a full, clear, and exact'description thereof. a c I,

My invention relates to" improvements in fluid fuel burners, particularly -that class which is adapted to be disposed in the fire box of a cook stove or similar heater.

Inasmuch as cook ranges differ greatly in size with a consequent change in the length V of their fire boxes,'it will'obvious'ly bean advantage to change a "burner heads to conform to the length of' the fire box. Therefore it is theprincipal" object of the present invention to provide a 7 "fluid fuel burner which is adjustable for use the position of the V in stovesor ranges of variouss'izes.

e It is also an object to "provide an improved simply constructed burner head which has means for trapping any scale or foreign matter before the fuel enters the discharge portion thereo'fi A further object is to provide meansfor increasing the efficiency of the initial generation of gaseous orvaporous fuel."

A San further object is to provide aiiiin .Fig. 2 is a longitudinal sectionalview taken substantially on the plane ofthe line 22 of Fig. 1 V I Fig. 3 is a transverse sectional view on the "plane of the line 3-3 of Fig.1, and

Fig. 4: is a detail plan vlew of theibase plate;

Inasmuchas my invention adapted for use in stoves, its specific application has? not been particularly disclosed. It will be seen from the following description, howi ever, that it may used'withany stove fe er l y,

without change, it being normally mounted on the usualgrate' when thestove has here'- tofore been used for burning coal or wood.

, Referring more particularly to the present embodimentof the invention, it will be noted that 1 indicates a flat base plate having depending peripheral flanges or walls 2 whiclrengage the grate bars, and a pair of longitudinally arranged oval air supply openings 3. These openings are positioned to "one side of the longitudinal'center of the base,whileto the "other side of such center and'at the opposite ends of the plate formed a pair of substantially semi-circular tudinally of the base;

: Associated with each of. the air "d'recting member 1 6," the lower end oreach of which being provided with a laterally extending flange? which has a sliding contact with the surfaceof: said base. These mem- 'bers' 6 arealwayspositiOned over the openflanges 4. Each of thejflanges has an open" end slot 5, said slots being; extended longi tpening's 3 is afrusto-conical air and flame" ings 3 so that allair entering the lowerpor tion of the"stjove or the like. inust pass throughthe same before reaching the burner "heads to be hereinafter described." For aidmg 'in the direction of such air to the opening e, the space between the edge of the base; and the walls of the "fire boxis closed withfsuitable material.

Ai burner fhead 8 is adapted to be em ployedin coimection with e'achair supply opening and its directing member. Since each of'these heads andtheparts of the invention which supply fuel thereto sub stantially alike, the description of one will "suiiice "for bothf, Theburner head 8 com-r prises anattaching arm 9, one end of which is open and integrally screwethreaded, while the other end is bent laterally for engage p'ositionedabove thefbase and approxilnatel'yintheplane ofthe top of the air di-- recting members 6. The arm 9, therefore, is

= 1 inclined downwardly and adj acent l its lower end has a gas discharge "armll' formed in therewith, said discharge arm bem tw th a sup ly d generating. pip

'fingfexten ded at right angles to the other arm "an'dlpositionedhorizontally; The discharge 'armis' disposed through alined openings in *the wall of one ofthe air directing members 516 airtime-e s P m re i fer n e e ei mally closed by a screw plug 12, which plug permits the head to be readily cleaned and also provides for the insertion of a cylindrical filtering screen 13 of reticulated ina-j' terial. As shown most clearly in Fig. 1, this screen covers the passage-Way between the arms 9 and 11 of the burner head, and inasmuch as such passage-way is spaced above the lower end of the attaching arm, any sediment which is separated from the fuel by the screen will fall uponthe plug 12 and be thereby trapped.

The end of the pipe 10 remote from its connection with the burner head is threaded in 'an elbow 14 which in turn is mounted on the upper end of a hollow standard Each ofthe standards 15 is adjustably dis- ,posed in one of the slots 5 so that the burner 7 heads may be moved toward or away from each other toaccommodate the burner for use invarious sizes of stoves or the like. Each standard is clamped to itsfflange 4 by clamping-nuts 16 threaded thereon asrmost yolearly shownin Fig. 2. The lower end of each standard is adapted to be connected by a union or the like 17 to the end of a fuel supp'ly tube 18, the control of whichmay ing to receive the standard ,which'is used .be located outside of the stove or in any other convenient location.

The present invention is designed primarily for use in connection with liquid fuel; therefore an initialgenerating means in the form of a pair of generator pans 1'9 is provided. Each of these pans has a c1r-' cular portion provided'with a central opentherewith, and a laterallyextending portion to underlie the adjacent end of the supply pipe 10. The generator pans will thus always maintain the same relative position V with respect to the standards and will be moved therewith. ...As is usual in devicesof this character, alcohol or other liquid fuel is disposed in the pans 19 for pre heating the liquid fuel within the standards 15.

Such fuel is obviously more quickly heated and therefore more readily vaporized when of small volume; therefore I dispose within each of the standards a rod 20, the diameter of said rods being slightly less than the inner diameter of the standards, The

lower .ends of the rods are beveled off as at 21 and seat on the ends of the supply tubes -.18. j A thin film of oil or other liquid fuelis thus disposed around each of the rods. 2

The burner heads are rendered more efficient and their operation more easily fconthe burner heads are adjusted total y-one of their several positions, and each is connected gated air supply opening, v member slldable over sald opening, a burner each air and g g p v 'tions. areelongatedso that theyliiay be used when r with a sleeve 23 that is journaled on a rod 24 between a pair of uprights 25 which rise from the base plate.

By thus pivoting the flame spreaders they may be readily adjusted toward or away from the burner heads thus regulating the amount of heat directed upon the supply and generating pipe 10. They may also be used for directing the flame toward the oven of the stove or range, or if the jet openings of the burner heads are to be cleaned, they may be readily swung upwardly and out of normal position. Such adjustment is procured through a crank 26 that projects from the sleeve 23'and a rod-27 pivoted thereto. Said rod extends through an opening in the front wall WV of the stove and has its end threaded to receive a winged nut 28, the adjustment of which varies theposition of the spreaders 22. 1
